feat: add system config import, refactor install script and nginx auth

- lib/system_import: new module to import system configs into JSON at daemon startup
- daemon/server.py: call import_all() during startup for config reconciliation
- daemon/handlers/nginx.py: simplify add_domain auth handling, remove duplicate code
- scripts/install.sh: replace inline Python setup with curl-based daemon API calls; apply IP forwarding at runtime
- hoover: bump internal asset versions to v=8
- pages: bump asset versions to v=9
